Jinzhou Yunxing Industrial Ceramics Co., Ltd. National Day holiday time: October 1st to October 7th. We normally accept order consultation during the holidays and arrange production after the holiday.

The application of alumina ceramics in modern society has surpassed our imagination, and its application has become more and more extensive. It has met our daily needs and special performance needs. Since the application of alumina ceramics is so extensive, let us take a look at the hardness of alumina ceramics.

As an important part of chemical instruments, crucibles are liquids for melting and refining metals, as well as for solid-liquid heating and reaction vessels. It is the basis to ensure the smooth progress of chemical reactions. Historically, crucibles were originally made of clay, and one of the earliest uses of platinum was also to make crucibles. But with the development of preparation technology, crucibles can now be made of any material that can melt or change its contents.​

Due to the relatively large increase in the coefficient of thermal expansion, the thermal shock stability is reduced. It can be used to manufacture insulating ceramic parts for ultra-high frequency and high-power electric vacuum devices, as well as ceramic shells and various ceramic substrates for vacuum capacitors.

Jinzhou Yunxing Industrial Ceramics Co., Ltd. Due to the increase in business volume and product categories, the company built a new factory. Now the appearance of the office building of the new factory has been completed.

(1) Easy to wash and keep clean. The glazed surface of the alumina ceramic crucible is bright and delicate, and it is easy to wash away after being contaminated. (2) Porcelain has very few pores and low water absorption. Use alumina ceramic crucible to store the solution. After the mouth is tightly sealed, it can prevent the solution from volatilization, penetration and external bacteria.

The current application of alumina ceramics in the market has far exceeded our expectations. The overall application of alumina ceramics is becoming more and more extensive, because it can not only meet the needs of our daily life, but also meet the needs of some special properties, although The application of alumina ceramics in modern society has been very extensive, so what are the main principles for choosing high-quality alumina ceramic rods? The following is introduced by the staff of Jinzhou Yunxing Industrial Ceramics Factory:

The ceramic material developed earlier is alumina ceramics. This material is resistant to high temperature and corrosion. It is an excellent and commonly used material. The material can be used to replace metal substances and extend the service life of the equipment. Increase the use of power.

Alumina ceramic tube sintering is a key stage of ceramic preparation, and the sintering atmosphere has a great influence on the preparation of ceramic materials. Too high sintering temperature or too long holding time will promote crystal growth, so that the fine raw materials will develop into coarse grains at high temperature, and the amount of liquid phase will increase. This will not only decrease the strength, but also weaken the wear resistance. Of course, if the temperature is too low, the sintered body will not be dense, and the wear resistance of the product will not be good.

Production practice and a large number of studies show that: low porosity, high density alumina ceramics have excellent structural properties. High density means that the crystal grains in the ceramic body are tightly arranged, and it is not easy to form destructive breakthrough points when subjected to external loads or corrosive substances.
